A further object of the invention is to produce a window: of the oh'aria'cter justides scribed, whereinatlea'st one of the sashimay be shifted to *a number of intermediate .posia tions affording ventilation 'openiiigs, s These andother objects weiattain by the drawings, wherein for the purpose lot/illustration is shown preferred embodiment of our invention and' -whereiM Flgure :1 :1s a transverse sectional view in accordance with our invention; v

Referring now more particularlyto the drawings, the numeral 10 generally desighates the stiles 'ofa window frame, providing the usual inner and outer channels 11' for lower and upper sash 12 and13. In accordance with our invention, within each ofthe's'e channels, we-m'ounta weather strip 14 in the'formof a trough, the bottom wall of-whichi's'secured to the base .of the channel and theside iwalls 15\of which have out turned flanges16 r 1 c Engaged with this weather-strip a rompressible strip, generally-designated at 17. This compressible strip comprises'a' :18 having upon 7 its weather-strip Econfrionti'ng faceuopposed channels 19 receiving the out-V turned flanges 16 o f:the-Weatherstrip aaiucl having at its-side edges walls 20.; Acover )*l-ate.-2'1 is provided having at its .s'ideedges walls22 slidably embracing the outer faces ofvthe walls .20 of the :slidable base plate 1.8. The coverjplate .21 is-formed; with longiconfronting face,;.the purposeof.v r-hich will hereinafter -appear. 1 u I 1 At al ongzitudmally spaced-points, the cover plate iQlmhfl'SfOlfllQd therein openings in which :are aifixecl' J nilts'; 23, into which are threaded bolts QlrWhl'Ch-fllfl directedthrough the base plate 18 andlhav'e metastases rotatahly seatedlih depressions formed a the outer face1o f this base plate, as at 2 6:

The ends voffthelloolts are slotted, as at 128, so that a screw-driver may. be employed in the inner' face of the 'cover'plate-to iadjllst f the maximum distance .betweienat'he' hate-and cover f'platesand accordingly the tension with which the springs force the coverplate into engagement with the sash.

At oneend, vboth the--base-,-pla te 18-,and cover plate 21 are reinforced by plat-c5129 and 30. ilnwtheshase and cover plates'wand reinforcing plates 29'i-and :30, .a'lignedfopen-V ings are for-med through which are 1 rotatahlv directedra shaft 31; "This shaft has Secured thereto a disk; 32, which :abuts the reinforcing plate .29 50f the :base :plate: 18 and inwardly of this: reinforcing plate" is squared. For this reason, the openings of'lthe reinforcing plate30 and the ic'ovlerjplate .21 will not be sealed by the shaft and accordingly a washer 33 fitting the'sha-ft andaof greater size than" the openings is interposed-between the cover plate and plate 3'0. Outwardly of the disk 32, the :shaft is roundaand fits the opening of'the base 2 plate through which it slots 35 limit'rotation of the shaft 31 to 90,

The disk has secured thereto. diapasses.

3 WlllCh extend metrically opposed lugs through arcuate slots 35 formed in the base plate 18 and its reinforcing plate 29, and into the trough of the weather-strip 14 The At the opposite end of the member 17, the base plates 18 are slotted with, slots136 opening through the ends l of the base plates and the inner end walls of these n'slots' are formed-to provide hooks 37 for engage- L Each sash includes-two side plates 39,

which are rigidly secured thereto and coact with the cover plates 21 of the resilient strip 17. These sash plates, as they may be termed, have longitudinally extending V- shaped ribs 40, which slide in the V-shaped grooves 22 0f the cover plates and the edges ofthe side plates are preferably provided with flanges 41 which engage the front and rear faces of the'sash frame andserve to conceal mechanism associated with the sash plate, as hereinafter described. 'Each sash plate, at its lower'end, is reinforced by a latch plate 42 and both the sash plateand latch plate are formed with a longitudinally extendingslot 43 or the same width as the squared portion of. the shaft 31. The sash frame is correspondingly grooved, sowthat the endsof the shafts 31 may extend there-i into. The latch plate 42 is located upon the sash confronting faceof the sash plate and has pivoted to its inner face at 44 a latch45, which will engage with the shaft 31 and hold it in the inner end of the slots 43. This latch is loosely mounted upon its pivot and so at tached thereto that when the sash is horizontally disposed, the latch will fall, by gravity, to a position where its bill clears the slot 43, so that the-shafts 31' may be engaged or dis-- engaged from the sash. It will 'be' obvious that since the'portion ofthe shaft whichengages thesash is square, the shaft will rotate as the sash is rotated. 5'

Secured to each stile channel is a plate46. This plate may be either directly secured to thebottom wall of the channelior be secured within the trough of the Weatherstrip. In the present instance, the plate associated with the lower sash channel, is located in the trough while the plate of the uppersash channel is secured directly to the-wall ofthe channel. Eachiplate 46 has avertically extending slot 47through which the lugs '34 and inner end oft-he shaft 31-may enter when he associated sash is vertically disposed. Each plate has associated with its slot 47 oppositely directed coves 48 into which the lugs 34 may extend to permit the sash to be rotated from vertical to horizontal position. When the sash rotates at horizontal position,

' neeaeea ,theselugs engage against the walls ofthe. I

cove and their movement is checked thereby.

This movement is additionally checked by V 7 sash channels are disclosed as having a 7' ,downward extension 49 having at vertically spaced points pairs of coves 50 and 51 into which the lugs-34 may move and the walls of I which checkmovement of the lugs when the sash has a slight inclination with respect to the window frame. c. These pairs of coves provide a means for setting the window at ventilating positions, such as that indicated in Figure 6. The lowermostcove of the pair 50 preferably aligns with the lower end of theslot so that this ventilating position finay' be 7 assumed without elevating the ,sash.

.xIt will be obvious that in a window (5011-,

struction of this character, thezord'inaryrattling noises resulting from loosenessof the sash will be eliminated, as'tlie springs of the compressible strips will maintain a con: stant and firm engagement between the plates Bland 39; The lower sash may be i swung to either of two ventilatingpositions,
